Just found out the newer Audi/Lambo V10 DFI motors are different than the older ones. Does anyone here know what year they changed the bottom of the motor? Here is a schematic for the most recent Audi R8 V10 motor which shows multiple drain plug bolts that need dropping vs the two of the older motor.

Doing my first oil change and had bonehead newbie question as to which bolts are for oil drainage. Have circled the ones i see on my 2013 560-2 motor: Two Standard bolts with crush washer at front and right side of motor and a biscuit bolt at bottom. Cheers and thanks
